@bkuhn the key word in my comment is 'retreat'. Apparently this person said "putting GPLv3 software in cars will kill people". Instead of extracting the substance from the license politics and making the case that safety is compatible with (or even requires) that car owners be able to install modified versions of software running on computers in cars, you took the license politics hook line and sinker, making facile claims about GPLv3 software never harming people (for what definition of harm? but nevermind, uninteresting) worthy of a TV soundbite but unworthy of any other form of discourse.
